Starting with 953c65ffdd, offloading to
the Hurd VM would be enabled by default. However, ‘root’ had an empty
password so any user on the host could connect to the VM over VNC, log
in as root, and potentially populate the host’s store from there. This
change fixes that.
* gnu/services/virtualization.scm (operating-system-with-locked-root-account):
New procedure.
(hurd-vm-disk-image)[transform]: Add
‘operating-system-with-locked-root-account’ when offloading.
